Featuring unique sun and submergence shields, the dBMACH3 is designed specifically for open channel flow applications. dBMACH3 is the first ultrasonic transducer with zero effective blanking distance beyond the nose cone, allowing it to be sited at little as a few millimeters from the high-flow level. One of the critical factors affecting the ultrasonic accuracy is the measurement distance, so by minimizing the distance, accuracy is maximized.
Operating at 125 kHz frequency the transducer provides high resolution and accuracy. Essential in open channel flow applications. The dBMACH3 can be used with the Ultra 4, 5 and TWIN when in open channel flow mode, or can be paired with the FlowCERT, all of which provide a typical accuracy of +/- 1 mm (0.039in). Resolution +/- 0.5 mm (0.019 in). Range 0 mm to 2.4 m (0 in to 7.9 ft).
